Jon Hunter 78ecc56247 PM / OPP: Fix NULL pointer dereference crash when disabling OPPs ... Commit 7d34d56ef3 (PM / OPP: Disable OPPs that aren't supported by the regulator) causes a crash to happen on Tegra124 Jetson TK1 when using the DFLL clock source for the CPU. The DFLL manages the voltage itself and so there is no regulator specified for the OPPs and so we get a crash when we try to dereference the regulator pointer. Fix this by checking to see if the regulator IS_ERR_OR_NULL before dereferencing it.
